SMASH-PREVENTER.

Specification of Letters Patent.

Patented Aug. 1, rain.

Application filed September 28, 1915. Serial No. 53,128.

To all whom it may concern:

Be it known that I, WILLIAM LoNzo, a! citizen of the United States, residing at Fitchburg, county of Worcester, State of Massachusetts, have invented a new and useful Smash-Preventer, of which the following is a specification.

This invention relates to a smash preventer especially adapted for use on cotton drop boxes looms, and the principal objects thereof are provide a device for this purpose in which the parts now used on the loom can be utilized to a large extent and which will involve very little additional expense and yet will be a positive and accurate device for this purpose.

Reference is to be had to the accompanying drawings, in which Figure 1 is a front elevation-of a portion of a loom with a preferred embodiment of this invention applied thereto; Fig. 2 is a.

front view of a portion of the smash preventer; Fig. 3 is an end View; and Fig. 4 is an end view showing the parts in another position.

The invention is shown as applied to a loom having the usual boxes 10 adapted to be raised and lowered to bring the proper shuttle into position for operation. A loom of this character ordinarily is provided with a protection rod 11 having a finger binder 12 on each end and provided with a spring 13 for holding these finger binders back against the shuttle binders 1 1. This is the ordinary and the cheaper arrangement.

I am aware'of the fact that the protection rod has in some instances been made in two parts, each with a separate spring and each operating independently of the other for th purpose of causing the finger binders to act for preventing the raising and lowering of the shuttle box. This, however, involves the addition of one spring and considerable expense in providing for supporting the two extra ends of the two protection rods at the center of the loom at a point where there is not much room. I avoid these difficulties and a material part of the expense in the following way. I leave the finger binder 12 on one end of the loom and make the protection rod in a single piece having a single spring. I then take the finger binder off the drop box end of the loom and in the place of it put the following elements. On the rod is fixed a hub 15 by means of set screws. This hub is provided with a pro ecting arm 16. Also mounted on the rod adjacent to this hub, but freely pivoted thereon, is a lever 17 corresponding in a general way with the finger binder that has been removed, but this finger binder is provided with a projection 18 at the bottom which receives a leather member 19 connected by a spring 20 with a strap 21 which is secured to a stationary part of the loom. By this construction it will be obvious that this finger binder is resiliently held against the shuttle binder independently of the protection rod. However, when it is forced forward by the shuttle binder its lower end will engage the projection 16 and turn the rod to a certain position so as to hold the finger binder 12 at the other end of the loom in the same position as the lever 17, that is, in such position as to lower the usual dagger 25. However, when the shuttle leaves the box 10 the shuttle binder behind the finger binder 17 yields and allows the latter to move back by the action of the spring 20. This has no effect whatever on the rod 11. It will be seen also that the oscillation of the finger binder 12 at the other end of the loom, due to the reciprocation of the shuttle into that box oscillates the protection rod 11 to and from its limiting position shown in Fig. 3, without afi'ecting the position or condition of the finger binder 17.

From what has been said the operation will be readily understood. When a shuttle enters the box 10 the corresponding binder forces the finger binder 17 forward and also in that case holds the finger binder 12 in the corresponding position so that it does not exert pressure on the shuttle binder at that end. When the shuttle leaves this box that shuttle binder is retracted and the spring 20 pulls the upper end 22 of the lefthand finger binder 17 inwardly with the shuttle binder. Its converging upper and lower end surfaces therefore come between the nearest two shuttle binders in the usual way and prevent the boxes from rising or falling until such time as the shuttle again enters its box on that side of the loom. It will be understood, of course, that the finger binder 12 does not constitute a part of this invention and that it has the same operation and functions as is usually the case.

It will be seen that I get all the advantages of the above mentioned double protection rod arrangement and secure a safe smash preventer by the addition of two simple and cheap castings in place of the comparative expensive bearing plate that only a single embodiment of the invention,

I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but

I/Vhat I do claim is 1. In a smash preventer for a loom, the combination with a single protection rod, and a finger binder fixed on one end thereof, of a finger pivoted freely on the other end of the rod and adapted to engage the shuttle binder on that end, and means for trans-' mitting a forward swinging motion of said free finger to the rod and the other finger. 1 2. In a smash preventer for a loom, the

combination with a protection rod extending substantially the length of the loom and a finger binder fixed to one end thereof, of a fingerpivoted freely on the other end of the rod and adapted to engage the shuttle binder on that end, means whereby a forward motion of the free finger will turn the rod, and yielding means independent of the Codes of this patent mav be obtained for rod for normally but yieldingly forcing the said free finger back against the shuttle binder independently of said rod and of the first named finger binder.

3. In a smash preventer for a loom, the combination with a protection rod, and a spring for turning it in one direction, of a finger pivoted freely on the rod and adapted to engage the shuttle binder, means whereby the said finger will turn the rod in one direction but not in the other and yielding means independent of the rod for normally but yieldingly forcing the said free finger back against the shuttle binder independently of said rod and spring.

l. In a loom, the combination with a movable shuttle box having shuttle binders, of a protection rod, a hub fixed thereto and having an arm projecting therefrom substantially parallel with the rod, a finger freely pivoted on the rod and having a projection adapted to engage said arm, yielding means for normally pressing forward said projection and forcing-the finger back into contact with a shuttle binder, said finger having means on the end for engaging between two shuttle binders to prevent their rise or fall when the operating shuttle is not in position therein.

In testimony whereof I have hereunto set no hand.
